| XX XX | Te oneonehaumākūraraunga (tiketike i mua, iti i muri) |
Hei tātai i te waehere CRC:
1. Ko te rehita moka-16 tatūkē he FFFF i roto i te hautekauono (ara, he 1 katoa).Karangatia tenei rehita ko te rehita CRC.
2.XOR te raraunga 8-bit tuatahi me te moka iti o te rehita CRC 16-bit ka hoatu te hua ki te rehita CRC.
3.Hurihia nga ihirangi o te rehita ki te taha matau ma te moka kotahi (ki te moka iti), whakakiia te moka teitei ki te 0, ka tirohia te moka iti rawa.
4.Mēnā ko te 0 te moka tino hirahira: tuaruatia te taahiraa 3 (nekehia ano), mena he 1 te moka iti rawa: kua XOR te rehita CRC me te polynomial A001 (1010 0000 0000 0001).
5. Whakahokia nga taahiraa 3 me te 4 tae noa ki te 8 nga wa ki te taha matau, kia tukahia te katoa o nga raraunga 8-bit.
6. Whakahokia nga taahiraa 2 ki te 5 mo te tukatuka raraunga moka-8 e whai ake nei.
7.Ko te rehita CRC te mutunga ka riro ko te waehere CRC.
8. Ina whakauruhia te hua CRC ki roto i te anga korero, ka whakawhitihia nga moka teitei me te iti, a ko te moka iti te tuatahi.
Tūhonohia te pūoko kia rite ki ngā tohutohu i roto i te tikanga waea, kātahi ka kōkuhu i te rangahau pūoko ki te oneone hei ine i te pāmahana, ka tuku mana ki te kaikohi me te pūoko kia whiwhi i te pāmahana wai i te wāhi ine.
1. Tena koa tirohia mena kei te mau tonu te kete ka tirohia mena he rite te tauira hua ki te kowhiringa.
2. Kaua e hono ki te hiko, katahi ka whakakaha i muri i te tirotiro i te waea.
3. Kaua e whakarereke i nga waahanga me nga waea kua oti te hoko i te wa e wehe atu ai te hua i te wheketere.
4.He taputapu pū te pūoko.Tena koa kaua e wetewete i a koe ake, ka pa atu ranei ki te mata o te pukoro ki nga mea koi, ki nga wai pirau ranei kia kore ai e pakaru te hua.
5. Tena koa pupurihia te tiwhikete manatoko me te tiwhikete o te rite, ka whakahoki mai me te hua i te wa e whakatika ana.
1.Ina kitea te putanga, ka tohu te whakaaturanga he 0 te uara, kei waho ranei i te awhe.Tirohia mehemea he arai mai i nga taonga ke.Kare pea e taea e te kaikohi te tiki tika nga korero na te raruraru waea.Tena koa tirohia mehemea he tika, he pakari te waea.
2.Mena ehara i te mea ko nga take o runga ake nei, tena waea atu ki te kaihanga.
